Description

Servo synchronous film-sending mechanism

Technical Field

The invention relates to the technical field of woodworking machinery, in particular to a servo synchronous film-sending mechanism.

Background

In a woodworking enterprise, in order to save space, raw material plates are generally placed in a stacking mode, the stacked plates are also placed in a working area when the plates need to be processed, the plates are automatically processed through a production line, and a piece sending mechanism of the production line is provided with a push block for pushing out the bottommost plate; however, both ends of the raw material plate are generally tilted, and the push block often cannot reach the ends of the plate and passes through the bottom of the plate, so that the production efficiency is affected.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: the technical problem that the traditional plate sending mechanism affects the efficiency of a plate pushing mechanism due to the fact that the two ends of a plate are tilted is solved.

The present invention provides a servo synchronous film-sending mechanism,

the device comprises a conveying belt, a first working position and a second working position, wherein the conveying belt is used for conveying a plate to the next working position;

the pushing block is arranged on the conveying belt, moves along with the conveying belt and is used for shifting the plate;

the storage bin is positioned above the conveying belt;

the height limiting plate is arranged at a discharge hole of the storage bin;

still include the negative pressure chamber, the negative pressure chamber is located the conveyer belt below, works as the conveyer belt drives the ejector pad removes to when the feed bin, negative pressure chamber negative pressure adsorbs the tip of panel.

The working principle of the invention is as follows: when the plates need to be processed, the stacked plates are placed in a storage bin, the height of the height limiting plate is adjusted, and only the bottommost plate is allowed to pass through; when the ejector pad moved to the feed bin, the negative pressure chamber adsorbed the tip of panel, down pulled down panel both ends, made the panel level and smooth around, and the push pedal can easily be released the bottommost panel, has solved traditional issue piece mechanism and has influenced production efficiency's problem because of the perk of panel both ends.

Furthermore, the conveyer belt is provided with a first through hole, the first through hole is positioned at the front part of the push block, and the first through hole is communicated with the negative pressure cavity. The front end and the rear end of the plate are covered with first through holes; when the plate runs to the height limiting plate, the first through hole is communicated with the negative pressure cavity, and the negative pressure in the negative pressure cavity adsorbs and pulls down two ends of the plate to enable the plate to be smooth front and back; the first through holes are arranged in the conveying belt direction to form waist holes, the area of the first through holes is increased, and the stress areas of two ends of the plate are increased.

Further, the negative pressure chamber sets up the feed bin below, when first through-hole follows the conveyer belt removes to form the intercommunication when the negative pressure chamber to the negative pressure adsorbs panel tip. Because only the negative pressure cavity below the storage bin plays an effective role, the design reduces the length of the negative pressure cavity and improves the utilization rate of the negative pressure cavity.

Furthermore, a plurality of second through holes are formed in the upper portion of the negative pressure cavity, and when the end portion of the plate is adsorbed by negative pressure, the second through holes are communicated with the first through holes. The structure is simple and the processing is convenient.

Furthermore, a driving mechanism for driving the height of the height limiting plate to change in the height direction is arranged on the height limiting plate. Under the condition of error, two plates can be passed through once below the height limiting plate, and when the plates and the height limiting plate are dead, the dead problem of card just can be solved by lifting the height limiting plate by starting the driving mechanism, so that the operation is simple and convenient.

Further, the driving mechanism comprises a cylinder and a linear guide rail which is obliquely arranged. The height-limiting plate is installed on linear guide's slider, and when panel striking height-limiting plate, because the power of the output of cylinder is less, the height-limiting plate can drive cylinder piston rod withdrawal one end distance, plays the effect of buffering to protection panel can not damage by collision.
